HEPA & Carbon Filtration

The Combination filter used in the Blue Pure 221 marks the current peak for air filtration technology. Built to combine both HEPA and Activated Carbon filtration it is effective against many different contaminants and allergens. This includes pollen, dust, PM 2.5, pet dander, smoke, mould, bacteria and viruses.

Its 99.7% effectiveness against allergens allows it to make a notable difference very quickly and it has an expected life of 6 months or around 4,380 hours of use. As a result, the Combination filter doesn’t need replacing too frequently and it can be easily to disposed of as it is widely recycled.

Quiet & Efficient Operation

To match the top purification quality offered by the 221, Blueair has worked hard to make it very efficient when in operation. As a result, at its highest level, it only uses 60 watts of power and at its lowest level, it works at a mere 30 watts.

That efficiency also allows the Blue Pure 221 to remain very quiet when in operation. When at its lowest level it can even operate at 31 dB, which is about the same as standard breathing in terms of volume. Therefore, this purifier is a great nighttime companion that is almost undetectable.

Optimised Filter Structure

The Combination filter used in the Blue Pure 221 also implements a gradient structure of ultrasonically bonded fibres, which allows for maximum airflow to be maintained while allergens are removed. The complex nature of this structure also prevents allergens from escaping back into the surrounding environment once they are captured.

Straightforward Controls

Beyond its impressive purification ability, the Blue Pure 221 is also very easy to control. It’s streamlined interface consists of just one button on the top of the unit. This single button is used to cycle between the 3 speed settings and even indicates when the filter cartridge should be removed and replaced.

Appealing Design

Moving beyond its technical elements, the Blue Pure 221 also makes an impact with its bold and colourful design. Built to be compact, it has a minimal form factor, which has been blended with clean and modern styling ideas to great success. Its colour can also be modified through optional pre-filter accessories.
